Wanted to mention that it's NOT illegal to purchase Canadian SugarTwin for import to US, as long as it's just a small amount for personal use. It's only banned from being SOLD in the US. As long as you're not planning to sell your stash , you're fine.

I recall reading a few years back where a group of online buddies decided to save on shipping costs by having one person place a large order which they'd divide amongst themselves on arrival. Uh oh . The shipment was confiscated by US Customs .. a few individual boxes = personal use; a few cases of 24 boxes each = "obviously" intended for commercial sale
